MEANS FOR POURING R DISCHARGING LIQUID FROM VESSELS.

SPECIFICATION forming part of- Letters Patent No. 416,494, dated December 3, 1889.

Application filed September 23, 1889. Serial a resident of London, in the county of Middlesex, England, have invented certain new and useful Improvements in Means for Pouring or Discharging Liquid from Vessels, (for which I have obtained Letters Patent in Great- Britain, dated April 18, 1887, No. 5,608, and in France, dated June 14, 1889, No. 185,774,) of

which the following is a full, clear, and exact description.

My invention relates to tea-pots, coffee-pots, tea-kettles, and other utensils of like character, and its object is to provide a receptacle from which hot liquids may be eaily poured or discharged when needed without moving said receptacle from its place, and also with out exposing the fingers of the operator to danger of being scalded by the hot steam.

The accompanying drawings, forming a part of this specification, illustrate my invention, Figure 1 being a side elevation of the receptacle, partly broken away, with my improvement in normal position; and Fig. 2, a vertical sectional view with my improvement in raised position.

Similar letters of reference denote corresponding parts in both views.

The receptacle a for the liquid may be constructed of any suitable metal and of any preferred general contour and is provided with the usual bail. As shown in the drawings, said receptacle is slightly larger at its upper than at its lower portion, and its spout 1) leads out of its lower portion next its bottom to insure a more complete discharge of its contents.

Centrally of the upper portion of the receptacle is provided a circular opening a, in which is fitted for vertical movement a bottomless cylinder (1, having an arched top 6, at the base of which is formed an annular flange f for limiting the downward movement of the cylinder, and at the center of said top is formed on its under side a circular projection h, which extends downward within the cylinder. Said projection is formed with two or more vertical passages la, extending through it to allow entrance of air to the cylinder and receptacle, as hereinafter explained, an d with No. 324,731. (No model.) Patented in England AprillS, 1887, No. 5,608, and in France June 14,1889, No. 185,774.

to slide a stem m, having at its upper end a finger-piece 71, against the under face of which rests aring 0, of rubber or other suitable packing material, and the lower end of the stem is encircled by a spring 19, bearing between the lower face of the projection h and a collar or stop 0" on the lower extremity of said stem. In its normal position the stem m is drawn downward within the projection h and cylinder dby the action of the spring 19, the packing 0 then resting tightly upon the mouths of the passages and preventing access of air to the receptacle.

a part of the liquid in the receptacle a, the operator grasps the finger-piece n and draws up the stem m, and with it, to some extent, the cylinder d, against the tension of the spring 19, thus uncovering the passages lo and allowure prevent the liquid from rising toa higher level than in the body of the receptacle. Upon releasing the finger-piece the spring reacts, forces the stem downward, and applies the packing to the mouths of the air-passages and tightly closes them, while at the same time the cylinder, descending by its own weight, compresses the air and steam in it and the receptacle. The air and steam, being prevented from escaping at the passages k, press upon the surface of the liquid and force it to find exit at and through the spout b. This operation is repeated, if necessary, until such quantity of the liquid as may be desired has been discharged from the receptacle, whereupon the cylinder rises to its normal position. It will thus be seen that the liquid may be discharged from the receptacle without removing the latter from its place and without danger of the scalding of the operators fingers by the steam, and that as the passages k are sealed by the packing-ring and the spout by the liquid no air can enter the receptacle to cool its contents.

It will be obvious that the position of the spring and packing-ring may be reversed, if found desirable, and the stem be pressed upon instead of drawn upon to admit the air, without departing from the spirit of my invention.

Having thus fully described my invention, I

a central vertical bore Z, in which is adapted ing air to enter the cylinder and by its press- When it is desired to pour out or discharge 4 receptacle having a discharge-spout at its 3. A liquid-pouring vessel consisting of a side and a central opening in its top, a cylinder open at its bottom and apertured at its top, adapted to slide vertically in said receptacle, and a spring-controlled stem adapted to slide in said cylinder, having a fin ger-piece and carrying a packing-ring, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two Witnesses, this 8th day of August, 1889.

WILLIAM HENRY PIKE.
